Tavily vs Perplexity API (Sonar)
Tavily returns ranked web results with content snippets optimized for LLMs to reason over. Perplexity's API (Sonar) returns a synthesized answer with citations, like ChatGPT with web browsing baked in. The right choice depends on whether your agent needs to do its own reasoning over sources, or wants a pre-chewed answer to display to users.

Feature-by-feature comparison
The verdict
Tavily fits the modern agent pattern: let the LLM fetch sources and reason over them. Perplexity fits consumer-facing Q&A where you want a polished answer fast. If you are building a LangGraph agent, Tavily. If you are building a ChatGPT competitor UI, Perplexity. Note that Perplexity was caught fabricating citations in 2025, so verify any answer before surfacing it to users.
Consider Scavio instead
Scavio gives you the same raw-source pattern as Tavily with structured SERP features (knowledge graph, PAA, videos) that Tavily lacks, plus Amazon/YouTube/Reddit endpoints in the same API. Your agent gets richer grounding without building separate integrations.
